Conservatory vs Extension: What Spaces Are Best for Each?
When considering whether a conservatory or an extension is the right choice for your home, it’s helpful to think about how you plan to use the new space. Both options offer unique benefits, but certain areas of your home may be better suited to one over the other.
Conservatories: Ideal for Living Areas, Dining, and Garden Rooms
A conservatory works wonders in spaces where you want to make the most of natural light and the beauty of your garden. They’re perfect for:
- Dining Areas: A conservatory can provide a bright and airy setting for family meals or dinner parties, especially if you’re lucky enough to have a view of your garden.
- Living Rooms: If you’re after a relaxing space to unwind with a book or enjoy the changing seasons, a conservatory offers a calm, nature-filled environment.
- Garden Rooms or Greenhouses: For green-thumbed homeowners, a conservatory can double as a space for indoor plants or as a home for your beloved houseplants, bringing the outdoors in all year round.
Extensions: Better for More Functional, Permanent Spaces
Extensions, on the other hand, are better suited to spaces that need to be more functional and permanent, such as:
- Kitchens: If you need more space for meal preparation or want to open up your kitchen into an entertaining hub, an extension is the perfect solution.
- Bedrooms or Bathrooms: Extensions allow you to add an entirely new bedroom, an en-suite bathroom, or even a home office that’s private and separate from the rest of the house.
- Family Rooms: When your growing family needs more room to spread out, an extension offers a flexible, long-term solution for creating larger living areas.
- Home Offices: With more people working from home, extensions can provide the perfect space for a home office that is separate from the hustle and bustle of the household.
What is a Conservatory?
A conservatory is a light-filled space typically made of glass or similar transparent materials, designed to bring the outdoors in. Often used as a sunroom, dining area, or even a greenhouse, a conservatory offers a unique way to connect with nature without braving the unpredictable British weather.

The Pros of a Conservatory
- Versatility
Conservatories can serve multiple purposes. Whether you want a tranquil reading nook, a dining area, or a playroom, a conservatory adapts to your lifestyle. - Bright and Inviting
With their large glass panels, conservatories let in natural light, creating a sunny, welcoming atmosphere all year round. - Low Structural Complexity
Building a conservatory is often quicker and simpler than constructing an extension. Most components are prefabricated, making the installation process more efficient. - Affordable Option
Conservatories are typically more budget-friendly than full-scale extensions, making them a popular choice for homeowners seeking extra space without breaking the bank. - Permitted Development
Many conservatories fall under permitted development rights, meaning you might not need planning permission, which can speed up the process.
The Cons of a Conservatory
- Limited Value Addition
Conservatories are often viewed as temporary structures by surveyors and may not significantly increase your property’s market value. - Temperature Control Challenges
Conservatories can get too hot in the summer and too cold in the winter. While advanced glazing options can help, they can also drive up costs. - Privacy Concerns
With their extensive glass walls, conservatories may offer limited privacy unless you invest in blinds or other window treatments. - Durability and Maintenance
Conservatories often require regular maintenance to prevent issues like condensation, draughts, or leaks.
How Much Does a Conservatory Cost?
Conservatory costs can vary widely depending on design, size, and materials. On average, a small conservatory might start around £15,000, while larger, more luxurious designs can exceed £30,000.

What is a House Extension?
An extension involves adding a permanent structure to your home, seamlessly blending with your existing property. From single-storey rear extensions to double-storey side extensions, the options are almost limitless. Extensions are ideal for homeowners looking to create tailored spaces that match their lifestyle.

The Pros of an Extension
- Increased Property Value
A well-designed extension adds substantial value to your home, making it an excellent investment. - Customised Design
Extensions offer the flexibility to create spaces that meet your specific needs. Whether it’s a spacious kitchen, an extra bedroom, or an open-plan living area, you can design it your way. - Long-Lasting Solution
Unlike conservatories, extensions are permanent structures that enhance your home’s functionality and aesthetic appeal for years to come. - Improved Energy Efficiency
Modern extensions are built to meet today’s stringent energy efficiency standards, which can help lower your heating and cooling costs. - No Need to Move
Extensions give you the space you need without the hassle and expense of relocating, saving on moving costs, agent fees, and stamp duty.
The Cons of an Extension
- Higher Costs
Extensions are a more significant investment, with costs typically starting around £2,000 per square metre. Additional fees for planning permission, building regulations, and design work can also add up. - Longer Project Timeline
Extensions require more time to design, plan, and construct, which might disrupt your daily life during the building process. - Planning Permission
Depending on the scale and location of your extension, you may need to apply for planning permission, which can add time and complexity to the project. - Short-Term Stress
Managing contractors, meetings, and construction can feel overwhelming. However, working with an experienced architectural team like DeVis Architecture can ease the process.
How Much Does an Extension Cost?
The cost of an extension varies depending on size, design, and location. For a standard single storey extension in London or Surrey, you can expect costs to range between £2,500 and £3,500 per square metre, covering basic structural work and finishes. Larger or more complex designs—such as kitchen-diners with bi-fold doors—can significantly increase your budget. Don’t forget to factor in professional fees, VAT, and hidden costs like drainage solutions or unexpected site conditions.
Choosing the right design and materials is important to control costs while achieving the desired result. Simpler projects, such as permitted development extensions, tend to be more budget-friendly, while wraparound or side return designs may require additional planning permissions and logistical work.

From understanding first and second fix costs to preparing for potential surprises, careful planning with an experienced architectural team can make all the difference in delivering a beautiful, cost-effective extension that enhances both your home and lifestyle.

Conservatory vs Extension – Which One is Right for You?
When deciding between a conservatory and an extension, it ultimately comes down to your budget, lifestyle, and long-term goals.
- Choose a Conservatory if:
You’re looking for an affordable, quick way to add a versatile space to your home, and you don’t need it to serve as a permanent, year-round living area. - Choose an Extension if:
You want to increase your property’s value, create a permanent addition, and customise the design to meet your specific needs.
